If this is the case that's really sad but not entirely a surprise. Last time I was there in the summer, I noted absolutely no progress or effort had been made on rebuilding the old restuarant aside from clearing the debris. Also, for a considerable time now, some property developer scum have been trying to get hold of the site for (I think) another bloody caravan park - guess they've succeeded then as usual (money talks).
I think the 05 runway has been reclassified to only about 350m earlier this year due to obstructions??? Can't recall the exact details, may have been a Pooleys guide update - feel free to contradict this if I'm wrong.
All the best to the Sandown staff anyway.
